In the first collaboration, "Swalla" with Jason Derulo, Nicki seems to take aim at Remy's 2014 jail release (at least according to fans), rapping, "I gave these b---hes two years, now your time’s up / Bless her heart, she throwin' shots, but every line sucks.”

The alleged slams continue on her collaboration wit Gucci Mane, "Make Love," where she subliminally spits, "Go against Nicki, it’s gonna cost ya / 'Cause now it’s f--- ya, intercourse ya / I rep Queens where they listen to a bunch of Nas / I’m a yes and these b---hes is a bunch of nahs / Trying to win a gunfight with a bunch of knives / I win, get off the bench and give a bunch of fives / I don’t see her / B---h, I’m the greatest, no Kendrick, and no Sia."

Today, Remy hit back with a 7-minute (!!!) diss track of her own called "shETHER," a play on Nas' Jay Z diss track "Ether", which begins with audio of Nicki screaming "Free Remy!"

The rapper slams Nicki on the fiery hip hop track, taking aim at the "Anaconda" singer's famous booty: "I told you I wasn’t talking about your dumb ass / It look stupid, you literally got a dumb ass… / Let’s be honest, you stole that line about b---hes being your sons / How you take my '09 jail tweet and run / Talking about bringing knives to a fight with guns / When the only shot you ever took was in your buns."

Remy also takes shots at Nicki's relationship with her ex, rapper Meek Mill, spitting, "I saw Meek at All-Star / He told me your ass dropped / He couldn’t f--- you for three months because your ass dropped / Now, I don’t think you understand how bad her ass got / The implants that she had put in her ass popped."

On Saturday afternoon, Nicki responded to Remy's "shETHER" on Instagram, sharing a screenshot of an article about the other rapper's "disappointing" sales.

Meanwhile, social media has lit up with reactions from fans of both sides. See some of their responses to the feud, below:
